PERL Support Under Apache2
My perl script will not work correctly when run from Apache2 but works
fine from the command line.
Apache2 invokes the perl script to use Net::LDAP to bind through
stunnel to another server.
It works perfectly from the command line but it fails to bind when run
via Apache2 on this Fedora System.
It works great from a Debian System using Apache2.
Actually it looks like it is never even invoking the stunnel process at
all.
I have nothing in /etc/hosts.allow and nothing in /etc/hosts.deny and I
have completely shutdown iptables during my test.
So, with those conditons is there any reason that perl through Apache2
would fail to attach back to the stunnel process?
I have tried this both with and without the mod_perl active in Apache,
so it may be more of a server issue not ALLOWing apache to connect to
the stunnel process, but I thought I would start here and beg for
suggestions.

Re: PERL Support Under Apache2
Posted by Jonathan Steffan <jo...@bandwidthmarket.com>.
Fedora 4 has SELinux enabled by default. This might be an SELinux issue.
Run the following command to test without SELinux:
#setenforce 0
If that fixes it, you need to tweak your SELinux settings for Apache.
You can email me for help if needed. Fair warning, reboot or 'setenforce
1' because you can rock your SELinux contexts while not enforcing. You
would then have to relabel... and that might be a pain in the rear.
